Successful Conservative Management of Bronchopleural Fistula after Intraoperative Bronchial Injury

A 64-year-old woman diagnosed as primary lung cancer was admitted for surgery. Right lower lobectomy and ND2a-1 nodal dissection was performed under video-assisted thoracic surgery( VATS). The membranous portion of intermediate bronchus was injured about length of 5 mm while dissecting subcarinal lymph nodes. The fistula was closed by knotted suture using 4-0 polydioxanone (PDS) and covered with pericardial fat pad. Although the postoperative course was uneventful and discharged at postoperative day (POD) nine, bloody sputum appeared and right pneumothorax developed at POD 11. Bronchoscopy revealed a slit-like bronchopleural fistula at intermediate bronchus. By continuous thoracic drainage, the fistula successfully closed at POD 13.
